An optical disk drive in your computer can spin a disk up to 10,000 rpm (about 1045 rad/s ). If a particular disk is spun at 352.9 rad/s while it is being read, and then is allowed to come to rest over 0.167 seconds , what is the magnitude of the average angular acceleration of the disk?

Answer:

Angular Acceleration=2113.17[tex]\frac{rad}{sec^{2} }[/tex]

Explanation:

Given Data

w (angular speed)=352.9 rad/sec

t (time)=0.167 sec

a (angular acceleration)=[tex]\frac{w}{t} \\a=\frac{352.9}{0.167} \\a=2113.17\frac{rad}{sec^{2} }[/tex]
